Monochromatic light passes through two slits separated by a
distance of 0.0332 mm. If the angle to the third maximum above the
central fringe is 3.21 degrees, what is the wavelength of the
light? __ nm

In a double-slit interference experiment, the slit separation is
2.29 μm, the light wavelength is 532 nm, and the separation between
the slits and the screen is 4.42 m. (a) What is
the angle between the center and the third side bright fringe? If
we decrease the light frequency to 94.8% of its initial value,
(b) does the third side bright fringe move along
the screen toward or away from the pattern's center and
(c) how far does it move?

Bichromatic light of wavelengths λ1=572λ1=572 nm and
